摘　　要：通过乳液相转化聚合法,制备得到阳离子型丙烯酸酯-醇酸树脂纳米复合乳液(WARSi),并研究了γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH-570)含量对乳液及其胶膜性能的影响.采用傅里叶红外、粒径分析及原子力显微镜对聚合物的分子和微观结构进行了表征,并研究了KH-570含量对胶膜热稳定性、耐水性及其漆膜应用性能的影响.结果表明:复合乳液粒径均为纳米级别,当w(KH-570)=1.86%,粒径最小为109.5nm且分布指数低至0.07;AFM图显示漆膜表面平整,粗糙度Ra为2.225;漆膜吸水率减低到1.5%,并具有最高的热分解稳定性.The cationic acrylate alkyd resin nano composite emulsion （WARSi） was prepared by an emulsion phase conversion polymerization method. The effect of the content of the γ methacryloxypropyltrimethoxysilane （KH 570） on the properties of the emulsion and its film was studied. Fourier transform infrared spectroscopy, particle size analysis and atomic force microscopy were used to characterize the molecular and microscopic of the polymer. The effects of KH 570 content on the thermal stability,water resistance and application per formance of the film were investigated. The results showed that the composite emulsions were all nano sized,when w（KH 570） =1.86%,the minimum particle size was 109. 5 nm and the distribution index was as low as 0.07. The AFM images showed that the film surface was smooth and the roughness Ra was 2. 225. The water absorption rate of the paint film isreduced to 1.5~ and has the highest thermal decomposition stability.
